Oh, so the drum triggers are a processed waveform containing velocity and perhaps some sort of envelope? In that case the CGS26 may do what you want. Ken >I took a look at the monostable approach. It made me realize that I forgot to >mention that the drum triggers are velocity se
2011-05-31 by Dennis Chang
I took a look at the monostable approach. It made me realize that I forgot to mention that the drum triggers are velocity sensitive. That is to say, the voltage waveform should be preserved and passed through to the MIDI brain. A monostable with logic gate wouldn't work, whereas

Hmm, I was hoping that the AND would join the intersection between the spike waveforms. Let's imagine two identical perfectly triangular spikes with 30V peaks but spaced 1ms apart. The bottom of the "valley" formed by the overlap of the waveforms (the tip of the resulting AND wav

I'm sure these are dumb questions but I'll ask anyway. 1) What are the purpose of the diodes in this filter? That said, I have two REV 1 boards that I am finally getting around to finishing, and I was just wondering why the extra 2 diodes were added in the new revision. After loo

I doubt the two drum signals would coincide for long enough to generate a useful output. I'd suggest firing off some sort of monostable and using a logic gate connected to that. Ken --- In cgs_synth@yahoogroups.com , "dchang813" wrote: > > Hi-- > > I've been looking for a way to

Hi-- I've been looking for a way to combine the AC voltages from two separate piezo transducers such that I can detect when both have been struck at the same time. The analog AND feature of the CGS26 seems perfect, but considering that the waveforms of drum triggers are typically

I have built a version of the module with revision 2 (8 knobs - 3 switches). If I understand the module right, is the following description how it should work? IN BYPASS MODE: -Channel "A" & "B" are duplicate suboscillators. -Each channel should output audio through either of the

OK Scott, going back to your roots here. I'm verifying that the revision #2 Sub Oscillator panel layout would work like this... The 1n5 (1500pF) caps are substituted for the 330pF caps now. Is this necessary to switch if using the rev 2 layout? Thanks, David Ryle

Thank you! I am having some issues though. When I first tested it I found myself having to put the gain on my mixer all the way up to hear the sound to desired levels. With no gain it is very very very faint. Everything is soldered in correctly and using a meter voltage is going

Some food for thought here, certainly! My only mixer now is an inherited Mackie 1202 VLZ, it has problems and I try to avoid using it. Also I imagine that my modular setup would be more portable and integrated if I build a small mixer into the system. Also thinking about a four-c

I designed a module as my final output module. It's a 3 input mixer with spring reverb and an A-440 reference oscillator. I figured this would allow me to mix everything together, and since it was the last stage, would enable me to "hear" my reference oscillator for tuning. I use

Something like the resistive dividers in the CGS60 would do the job of dropping the signal down to line level for feeding into a hi-fi amp or mixer. That is pretty much what I do. Ken >For quite a long time, I would have just a few circuits on the bench and play them through my o

Ian, Well, it was some time ago and I do not recall what I did to solve it. Usually my build errors were around missing to solder a connection (I solder fast and tend to overlook a joint every other board), shorting two joints or a screwed up tranny / IC. it might have been the c

My guess is that you have used one of the new breed of super-bright LEDs with a 3 volt drop. This circuit was designed around the old fashioned LEDs that had either a 1.6 volt or 2 volt drop. You could try putting 2 or 3 1N4148 in series instead of the LED. The LED was never mean
